All too often, corners are cut to meet price-points in the entry-level road bike market, but the Allez redefines what it means to be "entry level." Focusing on weight, refinement, and reliability like nothing else in its class, the Allez is the first to make these technologies accessible to everyone. Whether you're just getting into road cycling, commuting, or looking for a new bike, the Allez is just as performance-packed as it is versatile. - Not only does a lightweight bike feel better when you're climbing up a hill, but it's also essential when you're carrying your bike up to the 5th floor, and this was at the forefront of the frame design. With a redesigned E5 Alloy frame, the Allez features a class-leading weight. Aggressively thin-walled, yet tough tubes have been implemented to save weight and this results in over a 450g (1-pound) reduction in the frame and fork alone, when compared to some models of yesteryear. - Entry-level road bikes often feature either alloy or cheap carbon fiber forks that greatly detract from the overall ride quality. But with a full FACT carbon fiber fork, the Allez is better handling, smoother riding, and lower in weight—floating over rough chip-seal and carving through corners like a slalom skier. - For the geometry, we developed the Allez by utilizing our vast Retul fit database. This meant creating a geometry that's sure to cover a broad range of positions, while still providing the performance-minded handling you'd expect from your first bike. - This Allez also features integrated rack and fender mounts, allowing you to move weight off your back and onto a lightweight rack. This not only makes for a good road bike, but it also enables you to transform it into a fast commuter.

And with a Women's Fitness Geometry that's designed to keep you comfortable while you're burning up the miles, and features that are as versatile as they are efficient, you'll find yourself consistently needing to set new goals to achieve in your fitness quest. - Designed for women who want to mix adventure with fitness, the hard-working, sturdy A1 SL Premium Aluminum frame features our Women’s Fitness Geometry, so you’ll go faster with maximum efficiency, only without the discomfort of an aggressive ride position. The more comfortable you are, the longer you’ll ride. - An SR Suntour NEX fork w/ Fitness Brain technology features 55mm of coil-sprung travel that takes the sting out of bumpy terrain, while our Fitness Brain technology promotes more climbing and pedaling efficiency. - Braking duties are handled by Tektro HD-305/310 hydraulic disc brakes to ensure effective, consistent, and reliable power through any kind of terrain or condition.
